SPECIFICATION forming part of Letters Patent N0. 633,788, dated September 26, 1899.

Application filed June 24, 1899. Serial No. 721,708. (No model.)

useful improvements in shutter-locks, and

more particularly to that class known as outside shutters.

The invention has for its object to constructa lock, which will be hereinafter described,

thatwill retain the shutter at any angle desired and one that may be easily operated.

Briefly described,the invention consists of a segmental rack formed with a series of radial notches, the rack being rigidly secured to the window-sill, a keeper having its ends formed at an angle and which is secured to the inner face of the Window-shutters gravity-pawl piv= otally secured at one end in the said keeper, and a handle formed integral with the said pawl for operating the same, the operation of the pawl being limited by one end of the keeper. g

The invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described,- and specifically pointed out in the claim. In describing the invention in detail refer- 'ence is had to the accompanying drawings,

forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, in which- Figure l is a perspective View of a portion of the building, window frame, sash, and shutter, provided with my improved lock. Fig. 2 is a transverse vertical sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a plan view of the segmental locking-rack. Fig. 4 is a front view of the same. Fig. 5 is a vertical sectional view taken on the line 5 5 of Fig. 3. Fig. 6 is a top viewof the keeper. Fig. 7 is a rear elevation of the same. Fig. 8 is a detail view of the gravity-pawl. Fig. 9 is an enlarged vertical sectional view taken on the line 9 9 of Fig. 2.-

Referring to the drawings by referencenumerals, l'indicates the window-sash, and 2 the window-frame, having formed therein a recess 3.

The reference-numeral 4 represents the segmental locking-rack, said rack being connected by a bar 5, formed integral therewith, said bar having arranged thereon a boss 6 and having formed therein apertures 7. Badially-extending notches 8 are formed upon the upper face of the segmental rack.

The, reference-numeral 9 indicates a pivot secured to the under face of the shutter and adapted'to engage in the boss 6 of the bar 5.

'the pin 12 of the keeper, the lower engaging face being adapted to engage the notches 8 of the segmental rack. The recess .3 in the frame is adapted to receive the keeper and to admit the shutter to be brought to the position vflush with the front face of the frame. The gravity-pawl is. so arranged within the keeper as a to allow the handle 14 to extend upwardly above the keeper in'order that the same may be easily accessible.

The many advantages that are obtained by the use of my improved shutter-lock will be readily understood from the foregoing description but particular attention is directed to the fact that various changes may be made in the details of construction without depart ing from the general spirit of my invention.

10 the desired angle, and a curved handle formed integral with the said pawl and adapted to engage one of the angle ends of the said keeper for limiting the movement of the pawl, substantially as set forth.

In testimony whereof I affix my signature 15 in the presence of two witnesses.
